LAB 25
Motion of pulse

4.
What does a specific point on a slinky do as a pulse goes by?
Figure 2

6.
What is observed when two similar pulses
(same amplitude) are sent down the slinky, one from each end, oriented in the same direction, at the same time.
Figure 5

7. When pulses are generated from each end, do they pass through or reflect back from each other?

Figure 4
The superposition of two equal and opposite pulses on a coil spring. In the fifth picture they almost cancel each other.
